1. the strain clamp of a large-section lead comprises strain insulator aluminum pipe 8, strain insulator steel anchor 7, aluminium bushing pipe 11 and drainage wire clamp 9, it is characterized in that:

  • Described strain insulator aluminum pipe 8 is the structure of welding drainage plate 12 on the extruded aluminum tube;

    Strain insulator steel anchor 7 one ends are draw ring 71, and the other end is the steel pipe 73 that is used to grip large-section lead 1 inner steel core 2;

    Described draw ring 71 is connected by connecting portion 72 with steel pipe 73, and described drainage wire clamp 9 is for by making the aluminum pipe extrusion process, and drainage wire clamp 9 is crimped onto on the strain insulator wire jumper 10 and is used for delivered current;

    Grip steel core 2 parts of large-section lead 1 after steel pipe 73 crimping of strain insulator steel anchor 7, the draw ring of strain insulator steel anchor 7 is series-connected on the iron tower of transmission line by gold utensil;

    An end grips large-section lead 1 and aluminium bushing pipe 11 after 8 crimping of strain insulator aluminum pipe, and the other end grips the connecting portion 72 of strain insulator steel anchor 7;

    Described aluminium bushing pipe 11 replaces the adjacent outer aluminum steel 5 and the outer aluminum steel 6 of a part of length of large-section lead 1, and strain insulator aluminum pipe 8 is crimped on outer aluminum steel 6 and the aluminium bushing pipe 9;

    Drainage wire clamp 9 is connected with drainage plate 12 on the strain insulator aluminum pipe 8 by the bolt group and is used for the conducting of electric current;

    The steel pipe 73 of strain insulator aluminum pipe 8, aluminium bushing pipe 11 and strain insulator steel anchor 7 gripped large-section lead 1 after crimping was finished, and the weight load of large-section lead 1 is delivered on the draw ring of strain insulator steel anchor 7, the draw ring of strain insulator steel anchor 7 is connected to the transmission of finishing weight load on the iron tower by gold utensil again.The circulation path of electric current is on the large-section lead;

    the drainage plate 12 on lead aluminum steel 1 and aluminium bushing pipe 11, strain insulator aluminum pipe 8, the strain insulator aluminum pipe, drainage wire clamp 9 and strain insulator wire jumper 10.
